Wait a second - how in the hell??? (spoiler)

Good point! My theory is that when Muir wrote the order/instructions for the operation (or whatever he typed on the paper with the signature), he would of course have typed Gladys' number as the one where the operation Dinner Out can be confirmed. I don't know if this is so or not, maybe it's a plot hole - you make a good point.

Still, a really exciting, suspenseful and great movie, one of my very favorites!

A 'secretary' in this sense is not the secretary you see at the bank, or the local school. Most of these people are cleared as highly as the diplomats and agents that they serve-therefore they are privy to much more of the inner workings of things than their job title would otherwise indicate.

I imagine the authorization form that Muir forged would list his name and number as the primary contact. After all, Muir had commanded ops before. The Director's signature was on it, but it wouldn't be unusual for someone that high up to leave the details to his underlings.

I know this is a three years delayed response, lol, but I have to agree with the other posters. Stuff like contact information and dates on a contract are vastly overlooked since they should be automatic, so it was easy for Muir to put a different number without anyone really noticing unless they thoroughly examined the pages. Until now, though, I never even realized that plot hole.
